The "cut off your ear" line was only on the theatrical release and the soundtrack album.
There was also that line when Aladdin is trying to quiet Rajah down, the line people mistook as "take off your clothes". It was on the VHS and laserdisc, but it was altered in the Platinum DVD and I assume it's still altered on the Blu-ray?
Also, which issue of The Rescuers do you have, Andrea? The 1992 release or the 1999 one? There was that infamous nude centerfold in the apartment window, which only appeared on the initial pressings of the '99 version. It's more obscure than its VHS counterpart; according to someone on Home Theater Forum, the first Rescuers '99 LD pressing was recalled before street date. If the spine says "14793 AS", you have that version. If it says "17105 AS", you have the revised pressing.
IMO, the nude photo in The Rescuers isn't as high a priority as all this other stuff, I just thought I'd ask.
